Data Validator

This package contains various modules for validating different types of data. Below are the available validation modules:

Avaliable for while

• cnpjValidator: CNPJ validation.
• cpfValidator: CPF validation.
• getOnlyEmail: Extracts only the email or emails address from a string.
• identifyFlagCard: Identifies the flag of a credit card.
• isCreditCardValid: Credit card validation.
• isEmail: Email address validation format.
• passwordStrengthTester: Password strength test.
• validateBRPhoneNumber: Brazilian phone number validation.
• isValidImage: Image validation.

Usage

Here is an example of how to use the functions in this package:

from multiform_validator import (
    cnpjIsValid,
    cpfIsValid,
    getOnlyEmail,
    identifyFlagCard,
    isCreditCardValid,
    isEmail,
    passwordStrengthTester,
    validateBRPhoneNumber,
    isValidImage
)

Usage Example

print("Is email", isEmail("[email protected]")) # True
print("Get only email", getOnlyEmail("awdawd wadawd wda awd [email protected] awdawdawd")) # [email protected]
print("Password strength", passwordStrengthTester("aA1!asd@qd2asd")) # Strong
print("Is CPF valid", cpfIsValid("123.456.789-02")['isValid']) # False
print("Is CNPJ valid", cnpjIsValid("12.345.678/0001-09")) # { 'isValid': False, 'errorMsg': 'CNPJ is not valid' }
print("Is credit card valid", isCreditCardValid("5117 2161 1334 8362")) # True
print("Identify flag card", identifyFlagCard("5117 2161 1334 8362")) # Mastercard
print("Validate BR phone number", validateBRPhoneNumber("(11) 91234-5678")) # { 'isValid': True, 'errorMsg': None }

isValidImage Usage Example

import os
from pathlib import Path

from multiform_validator import isValidImage

# Resolve the file path
file_path = Path.cwd() / 'static' / 'uploads'
retrieved_file = file_path / filename

# Read the first 4 bytes of the file
with open(retrieved_file, 'rb') as f:
    file_buffer = f.read(4)

print(isValidImage(file_buffer)) # True or False

Functions signature

All params with default values are optional.

def isEmail(email: str) -> bool:
    pass

def getOnlyEmail(text: str, multiple=False, clean_domain=False, repeat_email=False) -> str:
    pass

def passwordStrengthTester(password: str) -> str:
    pass

defaultErrorMsgCPF = [
  'CPF invalid',
  'CPF must have 11 numerical digits',
  'CPF is not valid',
  'Unknown error',
]
def cpfIsValid(cpf: str, errorMsg=defaultErrorMsgCPF) -> Dict[str, Union[bool, str, None]]:
    pass

default_error_msgCNPJ = [
   'CNPJ invalid', 
   'CNPJ must have 14 numerical digits', 
   'CNPJ is not valid', 
   'Unknown error'
]
def cnpjIsValid(cnpj: str, errorMsg=default_error_msgCNPJ) -> Dict[str, Union[bool, str, None]]:
    pass

def isCreditCardValid(cardNumber: str) -> bool:
    pass

def identifyFlagCard(cardNumber: str) -> str:
    pass

default_error_msg = ['Invalid value passed', 'Invalid phone number', 'Unknown error']
def validateBRPhoneNumber(phoneNumber: str, errorMsg=default_error_msg) -> Dict[str, Union[bool, str, None]]:
    pass

def isValidImage(file_buffer: bytes) -> bool:
    pass
